Abstract
    The results obtained with the optimal interpolation and the Green's function assimilation method using two-dimensional wave spectra from ERS-l SAR wave mode imagette spectra are compared. The derived wind and wave corrections to the data of the wave model WAM are evaluated with independent observational data. Indications are found that, on one hand, the model winds and subsequently the model wind sea are occasionally overpredicted, and that, on the other hand, the modeled swell energy is underpredicted. The identification of these shortcomings will help to establish lasting improvements in the geophysical modelling of winds and waves for short-term forecasts as well as for climate predictions.
